From Designer Roberto Coin's "cento" jewelry collection, the shiny O "Cuori" diamond pendant 18kt yellow gold. Cento is Italian for 'hundred' as Roberto Coin has created a diamond like no other, with 100 facets. The result is unparalled fire and brilliance - the perfect symbol for your perfect love. Many have attempted to imitate these incredible pieces, but none have been able to produce this level of quality. Finished with Roberto’s fiery ruby set inside—his internationally recognized signature.
